Enables single-stranded DNA binding activity. Predicted to be involved in several processes, including DNA metabolic process; modulation by host of viral process; and regulation of cellular macromolecule biosynthetic process. Predicted to act upstream of or within glucose homeostasis and positive regulation of insulin receptor signaling pathway. Located in cytoplasm and nucleus. Orthologous to human NUCKS1 (nuclear casein kinase and cyclin dependent kinase substrate 1). [provided by Alliance of Genome Resources, Apr 2022]
